RÉSUMÉ

Objective:To explore the association between grip strength and cognitive function in elderly people aged 65 years and over.Methods:Information on grip strength, cognitive function, and lifestyle in the elderly population aged 65 years and over in Wuhan was collected by unified professionally trained investigators.A total of 533 study subjects aged(70.7±5.1)years were grouped by quartile into four grip strength groups of Q1(<18.6 kg), Q2(18.6~24.1 kg), Q3(24.2~31.1 kg), Q4(>31.1 kg).Multiple linear regression and Logistic regression analyses were used to analyze the relationship of grip strength with cognitive function scores and cognitive impairment.Results:The mean grip strength of the 533 subjects was(24.94±9.15)kg.After adjusting for sociodemographic characteristics, lifestyle factors, history of diseases, as compared with grip strength Q1 group, the linear regression coefficients(Beta value)of cognitive scores and 95% confidence intervals(95% CI)showed statistically significantly positive correlation[0.45(-0.36, 1.26)、0.40(-0.52, 1.32)and 1.19(0.07, 2.31), all P<0.05]only between cognitive scores and grip strength Q2、Q3 and Q4 value; and the odds ratio and 95% CI of incidence of cognitive impairment were 0.97(0.43, 2.21)for grip strength Q2, 0.79(0.30, 2.06)for grip strength Q3, and 0.22(0.05, 0.92)for grip strength Q4.Considering grip strength as the continuous variable, the risk of cognitive impairment was decreased by 6% and the cognitive score was increased by 0.07 with per 1kg increase of grip strength. Conclusions:The results of this study suggest that there is a positive correlation between grip strength and cognitive function in the elderly population, and a lower grip strength is related to increased risk of cognitive impairment.More attention should be paid to the grip strength of the elderly in the community.
